y COPYING-BOOK.

SPECIFICATION `forming part of Letters Patent No. 224,529, datedFebruary 17,:1880.

` Application filed November 20, 1879.

To all 'whom it may concern:

Be it known that l, SAMUEL HANO, of Boston, of the county of Suffolk andState of Massachusetts, have invented a new and useful Improvement inCopying Books; and I do hereby declare the same to be described in the yfollowing specication and represented in the i accompanying drawings, ofwhich- AFigure 1 is a transverse section of one of my improved books,such section showing the ari rangement of its leaves of tissue ortracing `readily torn froml thel portion inside or back of them.

The object of the invention is to enable a person,by writing on theupper of the thicker or non-transparent sheets, to produce, by means ofa sheet of offset paper laid between the tracing-paper sheetand thelower sheet of the pair of thicker sheets, and having on both sides ofit an offsetting coating, one offset fac-simile copy of the writing onthe lower sheet and another such offset upon the intermediate or itracing or tissue paper sheet, the oset of the the `upper of the threesheets, obtains at one latter sheet being on its under side and showing`through the sheet, so as to be read by a person looking at the upperside of such sheet, or that side on which the offset is not made. Theoffset of the lower sheet will be on its upper face.

Thus `it will be seen that by my invention or improvement the party, bywriting upon and the` same time the original written sheet i of thickpaper and two copies thereof, one of i whichis on tissue or thinnerpaper, and the other on paper of the same kind as the upper y sheet. Theupper of the three sheets is usually to be ruled or provided withguide-lines for the y writings upon it, besides which it may have anyproper heading printed on it, the lowest sheet being without any suchlines. The uppermost as well as the lowermost sheet of each consecutivethree sheets of the book I provide with a line of punctnres, extendingacross it from the upper to thelower edge of it, near its junction withtheback of the book, such `being to so partially separate from onepartof the sheet the portion or part to be written upon, or to receivethe writin g or offset copyl thereof, as to enable it to be readilydetached from the rest.

In using the' book a person should place the black or offsetting sheetbetween the thin or medial or tissue leaf' and the unruled or lower ofthe two thicker or other leaves, and he should write with a pen or hardpencil on` the upper surface of the upper or ruled leaf. This havingbeen done, he is to tear from the book the two thicker of the threeleaves, leavin gthe thin or tissue leaf in place.

The two thicker leaves thus separated from the book can be used as theperson may desire. Should the book be what is termed in trade anorder-book,77 the party or agent who `may take an order for goods willwrite it upon the upper of the three leaves, and afterward separate thetwo thicker leaves from the book,

and give one of them to the customer or party giving the order and sendthe other to the principal or party who is to supply the goods.

In Fig. 1 of the drawings, A represents 'a book made as described, a b cbeing the three leaves of each ofthe consecutive sets of leaves. Of eachof such sets, a and c are the non-transparent or thick paper leaves, andb the transparent or tissue or tracing paper leaf. gis the back, and d dthe two covers of the book, thc binding of the book being in any of themodes well known.

Fig. 2 shows the sheet a with its rulings cl and line e of punctures,while Fig. 3 shows the sheet c with its line c of punctnres.

I am aware that it is not new, and I do not claim as my invention, tomake a copy-book with all its leaves alike in thickness or substantiallyso, whether such be of transparent or translucent or tissue or ofnon-transparent or thick paper. Y

I am also aware that before my present invention what are termedcopy-books7 have been made with a number of sheets of writing or thickpaper and a like number of sheets of thin or tracing or transparent ortranslucent IOO paper, in which case there would be a sheet of one kindand a sheet of the other kind side by side throughout the book; but inmy iinproved book there are only halt the number of tracing-sheets thatthere is of the thicker or other kind of sheets.

The advantage which my book has over others, as described, is that anindividual is enabled to obtain by means of it two thickpaper sheets foreach writing, instead of only one of thick or one of thin paper, orthin-paper copies only, as heretofore, generally speaking, it being muchpreferable to have thick paper for the sheets to be extracted from thebook, and to retain in it the tissue or thin paper copying-sheet.

With my improvement the rulin gs or guidelines need be only upon theupper of the three sheets of each set throughout the book-that is, onthe sheet to be written upon by the pencil 0r pen.

A manifold order or letter book of my improved kind is of greatadvantage to merchants or others by affording such means of procuringtwo removable thick-paper sheets, on one of which the order or writingis made, and the other having upon it a fac-simile of such order orwriting, the other fac-simile on the thin or tissue paper sheetremaining undisturbed in the book.

What, therefore, I claim as my invention or improvement is as follows:

1. The new or improved manufacture of copying-book, substantially asdescribed, having a leaf, b, of tissue or tracing paper between eachconsecutive two leaves, t c, of the thicker or non-transparent paper,such being` for use, in manner as explained, with an offsetting sheet ofpaper having on'both of its sides the offsetting matter or coating.

2. A copying-book having a leaf of tissue or tracing paper between theleaves of each consecutive pair of thicker or non-transparent leaves ofsuch book, and also having one only of the latter leaves ruled orprovided with guide-lines.

3. A copying-book having not only a leaf of tissue or tracing paperbetween the leaves of each consecutive pair of the thicker or non'-transparent leaves of such book, but having in and across each of thelatter leaves aline of punctures arranged in c lose proximity with theback of the book, all being substantially as described.

SAMUEL HANG.
